i'm trying to run a query at night, and output the results to a file.  i 
think i have the syntax right for the proper output, but it now appears 
that my little automatic (cron) query ran IMMEDIATELY after the first 
command in the same cron file (a VACUUM of the same database) executed.  it 
didn't wait until it was finished.  besides guessing what time the vacuum 
will be complete, and scheduling the second command in a separate cron 
appropriately timed to run afterwards, is there a way to "stream" the two 
commands such that the second does NOT execute until the first one is 
complete??

thanks!  jt
